Calla lily plant named ‘Brasilia’

ABSTRACT

‘Brasilia’ is a new variety of calla lily plant having inflorescences with a white-colored spathe having a pink flush that produces 5-25 inflorescences per tuber. The height of the top of an inflorescence above the soil can reach up to 40 cm. The leaves are green with transparent maculations present and have a leathery texture.

Botanical classification: Zantedeschia sprengeri.

Varietal denomination: ‘Brasilia’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of callalily, botanically known as Zantedeschia sprengeri and hereinafterreferred to by the cultivar name ‘Brasilia’.

‘Brasilia’ is a product of a planned breeding program, which had theobjective of creating Zantedeschia hybrids for pot flower production ina wide range of colors with a large, classic flower shape. The breedingprogram began in 1989, and the new cultivar is a seedling selected fromthe crossing of a Zantedeschia sprengeri selection referred to as C02001(female parent, unpatented) with a Zantedeschia sprengeri variety named‘Odessa’ (male parent, U.S. Plant Pat. No. 18,833). ‘Brasilia’ wasselected in 2007 by the inventor in 't Zand, The Netherlands as oneflowering plant within the progeny of the stated cross.

The first act of asexual reproduction of ‘Brasilia’ by tissue culturewas performed by the inventor in September of 2013 in 't Zand, TheNetherlands. Subsequent asexual reproductions by tissue culture at thesame location have demonstrated that the combination of characteristicsas herein disclosed for the new cultivar are retained and reproducedtrue to type through successive generations of asexual reproduction.

The following observations, measurements and comparisons describe plantsgrown from 12 to 14 weeks in 14 cm pots in 't Zand, The Netherlandsunder greenhouse conditions, which approximate those generally used inhorticultural practice. Color references are made to The 2001 R.H.S.Colour Chart of The Royal Horticultural Society of London, except wheregeneral color terms of ordinary significance are used.

The present invention has not been evaluated under all possibleenvironmental conditions. The phenotype may vary with variations inenvironment without a change in the genotype of the plant.

The following traits have been repeatedly observed and determined to bebasic characteristics of ‘Brasilia’ which, in combination, distinguishthis calla lily as a new and distinct cultivar:

-   -   1. White-colored spathes with a pink flush;    -   2. Compact plant architecture; and    -   3. High inflorescence production.

Further, when compared to calla lily plant named ‘Snow Storm’ (U.S.Plant Pat. No. 28,122), the upper surface spathe color of ‘Snow Storm’varies between White Group RHS 155A and 155D, whereas the upper surfacespathe color of ‘Brasilia’ varies between White Group RHS 155A and 155Band has a pink flush that varies between Red Group RHS 54C and 55B.

Table 1 provides similarities and differences of ‘Brasilia’ to itsparents, Zantedeschia sprengeri selection C02001 and Zantedeschiasprengeri variety ‘Odessa’.
